“绿道——邻里”视角下建成环境对城市绿道使用的影响——以广州为例

Influence of Built Environment on Urban Greenway Use from the Perspective of Greenway-Neighborhood Relationships: A Case Study of Guangzhou, China

基于"绿道—邻里"视角,采集了广州典型城市绿道上的市民使用人数与类型等属性,并运用多元线性回归模型探讨绿道周边建成环境(人口密度和土地类型混合度)与绿道使用之间的关系。结果表明:绿道周边建成环境作为绿道使用的潜在来源地和目的地,影响着城市绿道使用效果,步行和骑行可达范围内的居住区人口密度和绿道周边土地利用混合度均可作为绿道使用强度的解释因子,两者的增加均会带来绿道使用强度的提高;除此之外,周边居民区收入水平、年龄和时间等变量对城市绿道使用也会造成影响。研究结果可为城市绿道建设提供直接参考。

In recent years,a large scale of greenways was constructed in China,which provides many new leisure and fitness spaces for citizens. Because residents in cities became the main users of these greenways,the spatial differentiation of greenway usage should be critically evaluated to obtain an optimized use pattern. From the perspective of greenway-neighborhood relationship,built environment surrounding greenways is assumed to serve as a potential source of users as well as a destination that attracts greenway use. To explore the association of greenway usage with properties of built environment surrounding greenways,this paper takes a typical urban waterfront greenway of Guangzhou as a case. Data such as greenway usage,activity type,etc. were collected by using floating bicycle technology. Multiple linear regression analysis was employed to explore the potential association of greenway usage with properties of built environment. Results show that there was a significant correlation between greenway usage and the surrounding built environment. Among the selected properties of the built environment that might influence the users’ travel behavior,population density and characteristics of land uses were the principle factors causing utilization differentiation by segment. The larger the population density or the larger the variation in land use,the higher the rate of utilization for walking and bicycling. In addition, social-economic characteristics,including age and income in the area accessible by walking and bicycling, impacted greenway use significantly,as did the land-use mixture and prevalence of richer or younger groups. Day-of-the-week also had an influence on usage of greenways,i.e.,weekdays attracted more neighborhoods onto the urban greenway than weekend during peak hours for walking and bicycling. These findings may help with urban greenway construction and provide insights for greenway route optimization.
